Composure's buff with AF3 is lackluster because there are very few spells that it works with since most of RDM's enhancing spells are selfcast. So really it only works on Haste/Refresh/Regen/Phalanx II. I know those are the ones that count but it's still a shame that RDM, the highest Enhancing Skill job in the game has the fewest enhancing spells to cast on others.
